RETAINING-VALVE FASTENING.

Application filed April 14, 1927. Serial No. 183,641.

My invention relates to retaining valve fastt-ining means and its objectis to reduce such fastening means to the most simple form possible andat the same time to secure the necessary vertical adjuslinie t of thevalve to coni iiensate for variation in the length of the valve pipe.This I accon'inlish. in the preferred fol-1n oil my device, by providingin valve with a pair of integral lugs. eaeh having a vertical slotcooperating ivith is send permanently carried by the wall of the car towhich the valve is attached.

In the accompanying drawings, which illustrate one form of retainin g1valve fastening made in accordance with my invention, l igure l is afront elevation; Figure 2 a side View; and Figure 8 is a top plan view.

The hody of the valve, iiiidimted at 5, is provided at each side with anintegral lug (S in Which is formed a vertical slot T. Passing throughthe end Wall 8 of the car adjacent to each slot is the short end of astud 9 divided into two parts by a collar 10. The project inp; portionof this shortend riveted over to form a head 11, thus securing the studin position on the car. This method of applying the stud not onlyinsures its permanent retention on the car but also ellectively preventsits relation when the nut. hereinafter referred to, is applied. Afterpassing through the slots 7 in the lugs 6 the long ends of the studs areengagi cd. by nuts 12 which secure the valve firmly in position. Theslots 7 permit of the necessary vertical at stinent ol the valve tocompensate for varations in the length of the valve pipe 13. In order tolock the nuts against accidental removal, I prefer to provide the endsof the studs with slits 14: so that the said ends Inay be spread by theinsertion of a suitable tool to adjustahlv secure the valve in positionon r the car.

A retaining valve having an integral part provided With a slot, incombination with retaining means carried by a car and engaging With saidslot to adjustably secure the valve in position on the car. 3. Aretaining valve having a 111;; provided with a slot, in combination witha stud perinanently secured to a car and projecting therefrom throughsaid slot to adjnstably secure the valve in position on the car.
